Abstract:
To investigate the association between HbA1C level and severity of coronary artery lesion in non-diabetic patients with coronary heart disease. This study was a retrospective and controlled study in a single center. 302 patients were enrolled. Coronary arterial lesion was confirmed by coronary angiography carried out in Tianjin Chest Hospital between January 2008 and November 2011. The patients enrolled should be non-diabetic with normal fasting blood glucose and HbA1C levels. The patients were divided into 3 groups according to the HbA1C levels, Group 1 (≤5. 5%, n=92),Group 2(5. 6%-5. 8%, n=94),Group 3(5. 9%-6. 4%, n=116), and the SYNTAX scores between the groups were compared. The predictive value of HbA1C in groups with intermediate and high SYNTAX score was identified by Logistic regression analysis while common risk factors such as sex, age, hypertension, lipid, and fasting glucose were adjusted. The SYNTAX score from Group 1 to Group 3 had statistically significantdifference(P<0.01). Simpleregressionwasusedtocalculatethecorrelationcoefficient(r=0.335,P<0. 01). Binary Logistic regression was used to confirm that HbA1C level was also associated with intermediate and high SYNTAX score(OR=5. 089, P<0. 05). In non-diabetic patients, the HbA1C level is associated with the severity of the lesion of coronary artery. The results indicate that a higher level of HbA1C seems to be an independent predictor to the prevalence of complex coronary lesions.
